new.familysearch

I am trying Ancestral Quest 12.1, it should work with new.familysearch, but here is my problem, I have over 12 databases with over 30.000 names, I am working with one of the databases where I am not in. I understand I haft to LINK ME first before I can use LINK/UPLOAD INDIVIDUAL, but if my name is not in the database, how am I going to use LINK ME?
